An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-45340 in the wild and no public exploit code.\n\nAffected product: n/a. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2021-45340/ (Markdown: https://insights.sbomify.com/CVE-2021-45340/index.md)","id":"CVE-2021-45340","markdown":"https://insights.sbomify.com/CVE-2021-45340/index.md","name":"CVE-2021-45340","record":{"aliases":["DEBIAN-CVE-2021-45340","GHSA-7xr9-9g9p-xmfp","UBUNTU-CVE-2021-45340"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Sixel image library","requires_auth":"none","summary":"Attackers can cause a denial of service via a crafted PICT file due to a NULL pointer dereference in the libsixel library.","user_interaction":"required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"libsixel","vendor":"libsixel"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"In Libsixel prior to and including v1.10.3, a NULL pointer dereference in the stb_image.h component of libsixel allows attackers to cause a denial of service (DOS) via a crafted PICT file.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Null dereference in n/a","id":"CVE-2021-45340","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in n/a","id":"CVE-2021-45341"},"packages":[],"prev":{"headline":"Privilege escalation in n/a","id":"CVE-2021-45339"},"products":["n/a"],"published":"2022-01-25","related":[{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2021-40656","kev_date_added":null,"published":"2022-04-08"},{"cvss_score":8.8,"headline":"Use after free in n/a","id":"CVE-2021-41715","kev_date_added":null,"published":"2022-04-08"},{"cvss_score":5.5,"headline":"Denial of service in n/a","id":"CVE-2022-27938","kev_date_added":null,"published":"2022-03-26"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Attackers can cause a denial of service via a crafted PICT file due to a NULL pointer dereference in the libsixel library.","url":"https://insights.sbomify.com/CVE-2021-45340/"}
